METALLIC SEAL,

SPECIFICATION forming part of Letters Patent No. 253,674, dated February 14, v1882.

Application filed September 14, 1881. (No model.)

To all whom t may concern Be it known that I, EDWARD J. BROOKS, a citizen of the United States, residing at East Orange, in the county of Essex and State of New Jersey, have invented a new and useful Improvement in Metallic Seals, of which the following is a specilication.

The presentinvention relates to the construction of the seal-disks of lead and wire seals 1o andthemodeofsecuringtheendsoftheshacklewires therein for sealing the doors of railway freight-cars, and for like purposes.

When a seal-disk is cast on one end of a shackle of my indented detective wire patented June 27, 1876, or a shackle of cable-wire or the like, as heretofore proposed by me, this end is rendered absolutely secure, and this cast-in style of seal has recently become popu lar, owing to the facility it affords for carrying zo and rapidly applying the seals, as set forth in the specification of my cast-in lead and tin seal patented August 23, 1881, Letters Patent No. 246,068; but prior to my present invention seals of said description were peculiarly liable to be left with the threaded end of the shackle insecure, owing to the great power required to compress the nearly-solid seal-disk sufficiently to cause its metal to ow into the indentations of the threaded shackle end. Attempts have 3o heretofore been made to avoid this difficulty; but, so far as I am aware, they have invariably involved an abandonment of the said advantageous cast-in characteristic, besides rendering the seal much more expensive and complicating the sealing operation, one or both.

My invention, hereinafter described and claimed, consists in a seal-disk of novel construction, in combination with a shackle-wire of the aforesaid description, for rendering a 4o cast-in lead and wire seal free from the aforesaid objections, and at the same time lighter, and consequently in this respect cheaper, and in its preferred forms materially easier both to thread and to press.

Figure 1 of the accompanying drawings is a perspective view of one of my cast-in lead and wire seals as furnished for use. Fig. 2 is a sectional face view thereof` threaded but unpressed, and Fig.-3 a view of the same from 5o below; and Fig. 4 is a face view, and Fig. 5 a

view from below, ofthe sa me seal pressed. Figs. 6 to 10, inclusive, are like viewsin series ot' another of my cast-in lead and wire seals as it appears before and after the pressing operation, illustrating modifications of my inven- 5 5 tion, Fig. 6 being a perspective view, Figs. 7

and 9 face views, the former in section, and Figs. 8 and 10 edge views from below.

Likeletters of reference indicate corresponding parts in the several ligures.

S S2 represent manufactured shackle-wires of different varieties, and D D2 seal-disks of different patterns, cast upon the respective shackle-wires insnitable molds. The shacklewire S is of the variety patented by me June 27, 1876, and known as indented detectix'e wire. In the example it is united with a Seal-disk, D, having in substance the characteristic of my improved seal-disk patented March 30, 1875, the straight ends a b of the shackle-wire beingcrossed at or near the center of the disk in the act of threading the last end, b, owingto the arrangement ot' the threading-aperture c, formed in the seal-disk for its reception, as illustrated by Fig. 2,which shows said aperture c in the plane of section with the threaded end b therein, so that when the sealdisk is properly pressed the crossed shackle ends will bytheirindentations interlock withinthe disk, asindicated in Fig.4. The shackle S2 is of cable-wire-such asis com monl y usedand is shown in connection with a seal-disk, D2, having its aperture c2 for the reception of the threaded end 11"" of the shackle-wire parallel to the cast-in end a2; but either variety of shackle-wire, or any other having indentatious or any equivalent thereof adapting one end to be simply cast in for securing it, may be used in connection with either pattern of seal-disk; and the latter, as regards the form of threading-apertures and means, if any be used, for interlocking the threaded shackle end with the cast-in end or with a lockingpiece of hard metal, may be of other styles.

For securing the threaded shackle end b or b2 within the pressed seal-disk,with or without the aid of interlocking, as above described, and for lightening the seal-disk and facilitating the threading and pressing operations, the sealdisk of either pattern or style is conroo structed with recesses d eor d2 e2in its respectivelateral edges, and substantiallyin the plane of the threading-hole c or c2, said recesses being adapted to be readily formed in connection with the threading-aperture by a core-bar or core-bars at the casting` operation. One of these recesses, d or d2, is in communication with said threading-aperture c or c2 at the lower end of the latter, and in the examples serves to shorten said aperture, which facilitates threading, while the threaded end b or b2 is readily bent into'it by a simple lateral movement, which is enstomaryin temporarily securing ordinary sealdisks preparatory to pressing, and the whole depth ot' the seal-disk is utilized as anchorage for the cast-in end. The other recess, e or e2, serves in connection with the former to lighten the seal-disk and to facilitate the piessing operation, while in pressing the bent threaded end b or b2 is securely embedded in the walls of said recess d or d2, so that stripping it is effectually prevented. At the same time both faces of the unpressed seal-disk are smooth, and the disk expands and receives a sharp impression, which may be of any description, as perfectly as it' it were not recessed, as illustrated in the drawings; and the improved seals, owing to soft-metal seal-disk constructed with recesses.

in its respective lateral edges, and with a threading-hole which extends into one of said recesses, and a suit-able shackle-wire, as herein specified, having a straight cast-in end heldin a solid portion ot' the seal-disk, substantially as herein described, for the purposes set forth.

In testimony whereof I affix my signature in 4presence of two witnesses.

ED WARD J. BROOKS.
